This application provides a supercritical carbon dioxide drying device, relating to the field of precision cleaning and drying technology. The device includes a storage tank, a drying unit, a gas-liquid separator, and a compression subsystem. The drying unit includes a pressure tank and a vacuum tank. A cleaning cylinder is installed through the pressure tank, and the cleaning cylinder contains a control chamber and a cleaning chamber. The cleaning cylinder has a liquid inlet. A first piston in the control chamber, driven by a first driving component, can control the connection between the cleaning chamber and the pressure tank through the liquid inlet. The cleaning chamber is connected to the vacuum tank via a connecting pipe and a first control mechanism. A second control mechanism is installed on the air inlet connected to the cleaning chamber. The pressure tank is connected to the storage tank via a booster pump and a preheater. The vacuum tank is connected to the gas-liquid separator via a first control valve and a first vacuum pump. The cleaning cylinder has an venting pipe connected to the cleaning chamber, and a second control valve and a second vacuum pump are installed on the venting pipe. This device can achieve non-destructive drying with a short drying cycle.

The utility model discloses a poultry manure drying machine which is transversely arranged at the air outlet position of a fan at the rear end of a chicken house and comprises a middle frame for laying a conveying belt, side frames located on the two sides of the middle frame and used for supporting the middle frame in an auxiliary mode, and conveying belt driving motors installed on the tops of the side frames. The manure discharging mechanism is installed in the side frame and used for cleaning the conveying belt, and the manure cleaning tail frame is located on the outer side of the side frame and matched with the side frame to be fixedly installed. The chicken house manure treatment device is used for treating chicken house manure, hot air exhausted by a chicken house fan is used for drying the manure, conveying, cleaning and drying of the manure are achieved through cooperation of the middle frame, the side frames, the conveying belt driving motor, the manure discharging mechanism and the manure cleaning tail frame, and the chicken house manure treatment efficiency can be effectively improved.
